ROTARY VALVE.

Specication of Letters Patent.

Patented July s, 191e;

Application led March 16, 1917. Serial No. 155.369.

To all whom t may concern: p

Be it known that I, GEORGE M. BACON, a citizen of the United States, and a resident of Salt Lake City, in the vcounty of Salt Lake and State of Utah, have invented acertain new and useful Improvement in Rocation, Serial Number 149549, iledgFebru-- ary 19, 1917 for a centrifugal separator formed may be in any desired number, and

whereinl the valves are arranged in the pe riphery of the drum or casing and are adapted to feed material .radially drum or casing while the latteris rotated.

An, object of the .present invention is to provide an improvedform of valve'wherefrom the in is eliminated the frictional contact of machined surfaces, and wherein the valvel head or body is packed efficiently in. the:1

casing. V y

Itis the further aim of the present invention to provide a valve of this type with a plurality of'packing elements which may be independently positioned and removed and a valve which is so constructed as to provide a plurality of pocket-shin j the peripheral surface thereof to efectva continuous feeding of material or'- the like -through the casing in predeter-- -mined quantities. p 35 The above, and various other objects and advantages of this invention-will be in part described, and in part understood, from the following detailed description of the present preferred embodiment, the4 same being' illustrated in the accompanying drawing wherein Figure 1 -is va side elevation of a valve head constructed according to the present Y Fig'. 3 is a the valve head taken through a pair of opinventio'n'.

Fig. 2 is a valve, a portion of the casing therefor being disclosed. A v Y v longitudinal section through posed pockets of the valve. Y

Referring to this drawing, 10"designates an elongated hub portion provided with a horizontal section-'through the iiuted peripheral surface the concavities ot` which extend longitudinally of the hub, and for-m.substantially a polygonal body member. The concavities of the ,hub 10 thus strips 12, the latter may provide pockets the inner walls of which are Itransversely concaved and form at their adjacent sides radially extending and outwardly tapering ribs or partition walls 11.

A packing strip'12 is placed longitudinally in each lateral pocket ofthe hub 10, and may be formed of leather,`of.the like,

- which is held to the configuration of the 4sides of the hub 10.

The ribs 11 fit between the innerfaces of each adjacent pair of packing strips 12, and project the adjacent edge portions of the packing strips outwardly to form partition walls 14 defining the lateral sides of the pockets. i

The valve head thus formed .is adapted to engage in the opening or Way formed .in the valve casing or Wall 16, and the free edges of the packing strips 12 areadapted to abut flat against the inner surface of the wall 16.- As shown in Fig. 2, the partitions or free edge portions 14 of the .packing strips fit snug against the inner surface of the wall 16 and seal the pockets or compartthe purpose of freeing the opposite end edges of the packing strips and effect the tight ysealing of the hubs in the casing 16.

of less length than that of the packing strips 12, and are of less width than the same to admit of the free movement of the end and lateral edges of the packing strips for sealing the hub 10 in the casing 16.

It is apparent that should the material used, injure any one 'or more of the packing be individually rethe like, and aI-'e com The Shapers or retaining plates 13 are also movedlfrom the hub 1.0.by detaching the adsides of the hub may be of any desired size, and when the valve is in operation, the pockets regulate the feeding of material through the casing or Wall 16 in predetermined quantities.

It is of course understood that the valve of this invention may be used for various purposes, and that various modications and changes may be made in the saine Without departing from the spirit of the invention, and being restricted only by the scope i of the following claims.

l. In a rotary valve, the combination of a hub provided with recesses in its opposite sides, and packing stri s fitted insaid recesses and having their ateral edges in contact to furnish sealing-*and pocket fdad finin elements.'

2. n a rotary valve, the combination of a hub provided with a recess in and extending the full length of its side and open at the ends of the hub, and a packing stri fitted in said recess against the inner Wal thereof and having its opposite edges rojecting outwardly from the hub to sealing and pocketdening elements.'-

3. In a rotary valve, the combination of a hub provided with a uted peripheral surface, and packing strips fitted to said sure face in the concavities thereof and having their lateral e ges inv contact to provide sealing and pocket defining elements.

4f. In a rotary valve, the combination of a hub providedv With longitudinal concavities in"its opposite sides, a plurality of pack-l ing strips fitting in said conoavities, Shapers secured against said packing strips to conform the same to the inner Walls of the con cavities, the adjacent lateral edge portions of said strips being held in abutting relation and extending radially from the hub to provide partition Walls defining pockets in the concavities and for sealing the valve.

5. l'n a rotary valve, the combination of a hub provided with a longitudinally ears paoklng stri crmv tting in said recesses,

reoaoce tending concavity in the side, a packing strip seated in said concavity, a Shaper engaging against the outer surface of said to conform the latter to the curvature o the inner Wall of the concavity, said packing strip being of greater length than the hub and extending at opposite ends beyond the hub, said packing'strip also having its lateral edges extending outwardly from the hub for sealin the same and .to provide pocket-defining e ements.

6. In a rotary valve, the combination ofa hub provided With longitudinally extending concavities in its opposite sides provid ing partition ribs between the concavities, packing strips extending longitudinally in the concavities, transversely curved plates fitting against the outerqfaces of said strips, securlng means for the plates engaging the hub for binding the plates against the strips to conform the latter to the inner Walls of the, concavities, said packing strips extending at their opposite ends beyond the ends of the hub, and said transversely curved plates terminating at opposite ends short of the extremities of the packing strips, said curved at their lateral edges short of the free edges of said packing strips to provide packing elements at opposite sides of the concavitles.

7. in a rotary valve, the combination of a casing provided with a substantially cylindrical chamber therein communicating through the opposite sides of the casing, a hub arranged concentrically Within the casing and provided with longitudinally extending recesses in its sides, packing strips Shapers engaging the packing strips to conform the same to the inner Walls of the recesses in the sides of the hub, and securing elements passing invvardly through the Shapers and the packing strips. and being supported by the hfub,

vsaid, packing strips extending at their lateral edges beyond the Shapers and adapted for contact with the inner Walls of said casing to seal the valve therein and to define a pocket between the lateral edges of each packing strip.
